Fully Automatic, Head Mounted, Hand and Eye Free Camera System And Photography
A Fully Automatic, Head Mounted, Hand and Eye Free Camera System and Photography are disclosed. The Fully Automatic, Head Mounted, Hand and Eye Free Camera System consist of three components: A) a Head Mounted Camera Header, B) a Portable Personal Computer, and C) a Hand Hold Controller. The component A (Head Mounted Camera Header) is composed of two set of Eye Ball Trackers/Range Finder/Digital Camera Headers. The component B (Portable Personal Computer) control Eye Ball Tracker and the Range Finder to determine the direction of eye sight and the distance between the eye and the target, and adjusts the lens of the Digital Camera Header to aim at and focus on target to take pictures or record video and to save the pictures or video to the storage of the Portable Personal Computer. The user control whole system by pressing the buttons at component C (Hand Hold Controller). The aiming, focusing, and the capturing procedure is automatic, continuous, and in the real time, and is a true process of “What you see is what you get (photo or video)”.
The head mounted commercial digital camera, camcorder and the photography.
BACKGROUND OF THE INVENTIONThere are lots of patents involving the head mounted camera, but none of them was really used commercially. The films camera is too big and too heavy to mount on the human's head. Although CCD and CMOS sensor are widely adopted, almost all of patents relate to head mounted camera are short of automatic aiming and focusing, thereby cannot capture the scenery the user's eyes are really seeing. The U.S. Pat. No. 6,307,526 proposed the idea of using eye tracker; but the size of lens, the visual field of the lens and the angle of the lens can be turn around are limited. Another weakness of this patent is that at least one eye of the user must gaze at the viewfinder constantly. This patent also not use Portable Personal Computer, lacks powerful compute and control ability to realize automatic aiming and focusing automatically, continuously and in the real time, lacks huge memory to store the pictures and video.
The current price of color CMOS digital camera header with 300,000 pixels and the range finder chip are few Dollars. The error of Eye gaze Analysis System (LC Technologies, Inc) is 0.45 degree, i.e. about 1.4 inch at 15 feet distance. Gaze direction is determined using the pupil-center-corneal reflection method and the image processing and gaze point calculations are performed in C++ software on a Personal Computer with Windows 2000. The first commercial product using material of artificial muscle (electroactive polymer) was on the market in January 2003, when Japan's Eamex began selling battery-powered plastic fish that swim around aquariums and look practically indistinguishable from the real thing. All these products have a characteristic that is they are small and light. All these technologies lay down a foundation for my invention.
SUMMARY OF THE INVENTIONThis invention integrates new technologies including CCD CMOS digital camera header, Eye Ball Tracker, Range Finder, LCD, and artificial muscle, with the most important technology—Portable Personal computer (including laptop, palm, PDA, small single board computer, even cellular phone and iPads) together to create the Full Automatic, Head Mounted, Hand and Eye Free Camera System and the Photography.
This System comprises a Head Mounted Camera Header, a Portable Personal Computer and a Hand Hold Controller. The Head Mounted Camera Header comprises two sets of Eye Ball Tracker/Range Finder/Digital Camera Header.
By using two Eye Ball Trackers to take the pictures of pupils and cornea of two eyes continuously, Portable Personal Computer calculates the direction of the eye sight using these pictures and controls two Digital Camera Headers to turn around such that the direction of optical axial of the Digital Camera Header is always following the direction of eye sight. Portable Personal Computer also controls two Range Finders to transmit and receive infrared ray, measures the distance between the eyes and the target, then controls the lens of Digital Camera Headers to focalize on the target. When users press the shot button on Hand Hold Controller, Portable Personal Computer controls Digital Camera Headers to take pictures and to save them in Portable Personal Computer, or controls Digital Camera Headers to start record video. Because using the powerful Portable Personal Computer, all of the processes are automatic, continuous, and in the real time.
User do not need hold the camera in hand, no longer worry about the aiming and focusing; at any condition and any moment, just push a button, the scenery in user's eyes will be captured. This is a true process of “What you see is what you get (photo or video)”. The user will never miss any wonderful or any important scenery. Because all of the processes are automatic, continuous, and in the real time, this is also a very easy and convenient way to take picture or record video, and suit for anybody from child to older, even disabled.
BRIEF DESCRIPTION OF THE DRAWINGS
As showed in
The Eye Ball Tracker 4 comprises a support frame 43, an infrared LED 42 and a CMOS camera 41; the infrared ray from the LED 42 irradiates eyes, the camera 41 take the infrared picture of the pupils and corneas of the eyes always and transmits these pictures to Portable Personal Computer, Portable Personal Computer calculates the direction of eye sight automatically, continuously and in real time.
The Face Camera 9, which is located at center of two Eye Ball Trackers and fixed at the Install Base 1, comprises a support frame 92 and a CMOS camera 91. Face Camera always takes picture of the user's face. If the picture changed, it means the Head Mounted Camera Header moved, Portable Personal Computer will tell user using Speaker 39 to adjust the location of Head Mounted Camera Header with the help of Head Mounted Display if the movement is too big. The Head Mounted Display can be mounted onto and unmounted from the Slip Blocks 7 easily. In normal usage, Head Mounted Display will be taken off from the Slip Blocks 7.
